Create a BowlingTeam class The class has 2 fields: a field for the team name and an array that holds the team members’ names. Create get and set methods for the teamName field. Add a setMember method that sets a team member’s name. The method requires a position and a name, and it uses the position as a subscript to the members array. Add a getMember method that returns a team member’s name. The method requires a value used as a subscript that determines which member’s name to return. Create a BowlingTeamDemo class. In the main method include the following: Declare 2 variables: name and a constant NUM_TEAMS that holds 4 Bowling Team objects. Declare and instantiate an array teams of BowlingTeam objects. Using nested for loops, prompt the user to enter the 4 team names and enter the team members’ names. Using another nested for loop, output each team’s name and their team members’.
